j which the" following is a specification.

. The object of my invention is to provide means for operating the sidedoors of the a platform of a'passeng r car -which will be clear ofthetpassageways leading to and from the body of the car and yet willbeeX- posed so that in the event ofrepairs access may be readily had tothe apparatus.

in the accompanying drawings:- Figure trating my invention; Fig. 2, is aplan view owing the doors in the open position; Fig. 3, is a plan viewshowing the doors in a closed position; Fig. 4t, is a vertical seotionalview through the operating device,

and Fig. 5, is a detached perspectiveview of the device illustrating a.detail of the invention. i I

A. is the body of the car.

B is the platform having the usual front.

vestibule casing B and G is the roof of the platform. In the presentinstance the platform isopen at one side and this side is closed by apair of double doors D and E.

- Both doors may swing outward, as indicated pin 9 and to the arm dinFig. 2, of the drawing. The doors are pivoted at cZ and 6respectively, and these pivots are in tllefOrlll of rods which extend,in the present instance, the full height of the door, and at theupperend of these rods are arms (Z and e.

F is a bearing secured to the plate F and attached to the roof of thecar. Mounted in this hearing is a vertical shaft G carrying the ropesheave g at its lower end. upper end of the shaft is a head 9, whichrests upon the bearing. and in the present instance there is a ballbearing a mounted between this head and the bearing. rope 72, passesaround'this rope sheave and on each end of the rope is a hand hold. Theropes passing around the grooved guide rollers 7o, mounted in bearings,f, in the present instance, independent of the bearing F. Projectingfrom the under side of the sheave are two pins g 9 to which rods n, nare attached-one rod 7 being attached to one on the pivot rod cl,

while the other rod 72 is attached to the noonornaarme resentment.

pin 9' and to the arm 0- onthe pivot rod 6 sothat when the sheave 1srotated-first in onedirection, the doors will be opened, and

when rotated in the opposite direction, the doors will be closed.

The rods n, a. are so formed that the pins can pass the'center linedrawn through the pivot of the arms and through the shaft, thus lockingthe doors in the closed positionf Projecting from the bearing F is astop and on the sheave g are lugs m. One ofthese lugs contacts with. thestop when the sheave is turned in one direction and the other lugcontacts with the stop when moved in the opp.site direction. lvr'lountedin the stop in the present instance are cushions of rubber or otl eryielding material. Mounted on an extension 2) of the shaft G is a cup orshield P, which is arranged to catch any oil that may drip from thebearings.

The. doors are made in two sections and the doors open outward, in thepresent instance. The sections D and E are mounted on the pivots (Z anda, while the sections D and E are pivoted respectively to the outer endsof the sections D and E and fold inward. Onthese sections D and E arepins or rollers (Z and 6 which travel in an overhead guide rail C at theroof of the car. The lower ends of the doors may also be provided withrollers, which travel in guideways, but this is not absolutelyessential.

The operation of the mechanism is as follows :'VVhen the doors are open,the hand holds are in the position illustrated in Fig. l, and theconductor is located on the platform in close proximity to the handholds and by simply pulling down on the one which is the highest thesheave is turned and the doors are moved to the closed position andpreferably locked automatically. Vhen it is necessary to open the doors,the other end of the rope is pulled down, causing the sheave to turn inthe opposite direction, and the doors are thus moved to the openposition.

All of the mechanism, with the exception of the two depending ends ofthe rope, is

above the head line of the car platform, and

the ropes are located in close proximity to cJi the passengers enteringor leaving the car.

The combination in means for operating passenger car do0rs,-of anoverhead bearing, a vertical shaft in the said bearing having a headresting on the bearing, and a sheave secured to the shaft under thebearing, pins on the sheave to which the rods are attached leading tothe doors to be operated, a stop on the bearing, and lugs on the sheavecontacting With the stop to limitthe movement of the sheave, and meansfor rotating said sheave to operate the doors.
